HOW it's done

LIKE ORDINARY INTERVALS — ONLY LONGER

We run a 10 k every 3 hours over a 24-hour period (everyone starts at the same time, regardless of where you are on our planet), 

If you manage to complete all of the intervals you’ll end up with 80k (almost 50 miles) during 24 hours.

Everyone starts at the exact same time all over the world, which means that some start in the middle of the night, while others start in the afternoon.

Please see example starting times below.

YOUR CHALLENGE

PARTICIPATE ON your OWN LEVEL

This is no competition, this is a challenge where everyone participates on their own level. It means that even if you think your limit is 5, 3 or even 1 interval, you’re still welcome to participate. 

In fact, you’re more than welcome to run shorter than 10k, or mix it up with an hour of swimming, an hour of yoga, strength training or playing football with the kids. The important thing is that you move your body, in any pace and way you like. As long as you start your training at the collective starting times, you’re in the challenge!

meet up

To make it even more fun, everyone comes together on the Facebook event page.

This is a day and night filled with pep-talks and stories from your fellow ultra-interval runners out there — all trying to complete the same challenge, at the exact same time!
